PalaciosThe University of New Mexico, Albuquerque, NM 87131, USAJournal Article20161102For any simple connected undirected graph, it is well known that the Kirchhoff and multiplicative degree-Kirchhoff indices can be computed using the Laplacian matrix. We show that the same is true for the additive degree-Kirchhoff index and give a compact Matlab program that computes all three Kirchhoffian indices with the Laplacian matrix as the only input.https://ijmc.kashanu.ac.ir/article_48532_4ea24f618de4aee3f2e5feaf2ad0c8ca.pdf
